Where is the indicator mark on our trucks? I looked all over for it and I can't find it. Also, where should I disconnect the tan wire for the ETC? I looked for it in the engine compartment and can't find it. I can see it under my carpet in the passenger compartment, but I don't know if there is a plug for it or whether I have to cut it. If any of you could help me, it would be greatly apprectiated.
